Help me select my master cylinder

[Che70velle]

Guys I need to pull the trigger on my master cylinder. I THINK I'm gonna run power brakes, at least that's my plan as I write this, unless you guys talk me out of it. I have wilwood 6 piston calipers on the front, and 4 piston on the rear. My piston area for my front calipers is 5.06". My piston area for my rear calipers is 3.00".
This is gonna be a 95% street cruiser, and will dodge cones only occasionally.
I've had my eyes on the CPP MCPV, for a while, but I don't want to buy the wrong unit. Should I go with a Wilwood master, and prop. valve, and why?
I have the stock pedal assembly, going back in, so no change in motion ratio.
I need help determining bore sizing, and which brand works for you guys. Car is 70 Chevelle, if that matters.
Thanks in advance!
